Setup
Platformio.ini changes
In the platformio.ini
file, uncomment the TFT_eSPI
line within the [common] section, under lib_deps
:
# platformio.ini
...
[common]
...
lib_deps =
...
#For use of the TTGO T-Display ESP32 Module with integrated TFT display uncomment the following line
#TFT_eSPI
...
Also, while in the platformio.ini
file, you must change the environment setup to build for just the esp32dev platform as follows:
Add lines to section:
default_envs = esp32dev
build_flags = ${common.build_flags_esp32}
-D USERMOD_ST7789_DISPLAY
Save the platformio.ini
file. Once this is saved, the required library files should be automatically downloaded for modifications in a later step.
TFT_eSPI Library Adjustments
We need to modify a file in the TFT_eSPI
library. If you followed the directions to modify and save the platformio.ini
file above, the User_Setup_Select.h
file can be found in the /.pio/libdeps/esp32dev/TFT_eSPI
folder.
Modify the User_Setup_Select.h
file as follows:
- Comment out the following line (which is the 'default' setup file):
//#include <User_Setup.h> // Default setup is root library folder
- Add following line:
#include <User_Setups/Setup_ST7789_Display.h> // Setup file for ESP32 ST7789V SPI bus TFT
- Copy file
"Setup_ST7789_Display.h"
from usermod folder to/.pio/libdeps/esp32dev/TFT_eSPI/User_Setups
